The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X160-100 is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 100 mm range without swapping the cylinder. Ø63mm bore, 160mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X160-100 is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke, providing a nominal 160 mm maximum reach that can be shortened by up to 100 mm via the rear-cap adjusting screw. With a 63 mm bore, it delivers a robust 1559 N of push force at 0.5 MPa, making it suitable for medium-duty clamping, pressing, and positioning tasks where the end-stop needs fine-tuning during commissioning or changeovers.
This tie-rod cylinder uses a 20 mm diameter piston rod and PT1/4 ports, with an adjustable air cushion to decelerate the piston smoothly. The body length A for the SCJ series in this bore is 197 mm, and the cylinder operates reliably on filtered air from 0.15 to 1.0 MPa. The 100 mm adjustment range is ideal for applications requiring a significant degree of stroke-end variability without swapping the actuator.

Specifications follow the official AirTAC SCJ (adjustable-stroke) datasheet. The rear adjusting screw sets the stroke end position; force is the same as the equivalent single-rod SC bore. Confirm against the product label before installation. Thread options: PT (standard) / G.
| Pressure | Push force | Pull force |
|---|---|---|

| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
SCJ is single-rod, so force matches the equivalent SC bore: push uses the full bore area, pull subtracts the rod area. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Related types: SC (single rod, fixed stroke), SCD (double rod), SCT (multi-position). SCJ mounting: Basic, FA, LB, TC, TCM1. Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
The 100 mm adjustment range allows engineers to precisely dial in the stroke end position during machine commissioning, eliminating the need for fixed mechanical stops and reducing setup time.
Ideal for packaging or assembly lines running multiple product sizes. The stroke can be quickly re-adjusted by an operator to accommodate different box heights or part positions without replacing the cylinder.
In high-cycle applications like pressing or clamping, the adjustable screw can be used to take up mechanical wear on tooling or seals over time, maintaining consistent end-position accuracy and process quality.
Select the SCJ63X160-100 when your application requires a stroke that can be mechanically adjusted on the machine. If you need a fixed, non-adjustable stroke, the standard SC63X160 is the direct alternative. For higher force requirements, stepping up to an 80 mm bore provides 2513 N of push force at the same 0.5 MPa pressure; for a more compact solution, a 50 mm bore offers 982 N. The replacement match must be an AirTAC SCJ cylinder with a 63 mm bore, a 160 mm nominal stroke, a 100 mm adjustment range, and PT ports. For this 160 mm stroke, ensure the load is guided to prevent excessive side-loading and rod bending.
Adjustable-stroke checklist
At an operating pressure of 0.5 MPa, the cylinder provides a push force of 1559 N and a pull force of 1402 N. The pull force is lower due to the area of the 20 mm piston rod. The maximum push force at 0.9 MPa is 2805 N.
A screw mechanism in the rear cap allows you to shorten the cylinder's maximum stroke end position by up to 100 mm. This is a mechanical stroke limiter, not a force or speed control. The nominal 160 mm stroke is the maximum achievable when the screw is fully retracted.
